This is a good one. I think it should be C. The information is based on companies that have been operating for at least 20 years, is not an accurate representation of the ages of CEOs in general. There might younger companies with younger CEOs. Perhaps CEO's age just corresponds to the age of the company.

Agree with (C): General trend means that same should be true for younger companies. but no information is given about them.

IMO, Answer is C.

Even though the sample size is large, the fact that the study only only incorporates companies that have been around for 20+ years. The conclusion then states that " CEO's of companies in general now tend to be older ", but it does not consider companies that have been around for a shorter period of time.

Re: CEO Age [#permalink] New post 02 Dec 2009, 07:35
The question states in a large sample the CEO's are on average 8 years older than they were 20 years ago. Because the question already tells you that a large sample is used, knowing the exact number of firms in the survey to determine whether the study is viable or not is not necessary. Also, so what if you know the number of companies that took the survey. That information is useless because you don't know how many firms out of how many considered took the survey. For example, if you know 50 firms took the survey. Is it 50 out of 100 firms or 50 out of 10,000.

Good one.
I picked A initially but then realized it was the generic picture that needed identification
C is correct

i don't think that c is correct because there is no information about the operating years of a company...

It's an inference you can make. The passage says the average age of CEOs at a large sample of companies is 57. The average age at THOSE SAME COMPANIES 20 years ago was eight years younger. Therefore, the companies have to still exist in order to be surveyed (atleast 20 years old).

Re: The average age of chief executive officers (CEO s) in a [#permalink] New post 23 Mar 2015, 19:03
The argument concludes that: CEO's in general tend to be older now.
The basis for this claim is that:
1. Avg age of CEO in a large samples of companies is 57.
2. Ava age of CEO in these companies 20 years earlier is 57 -8.

A & B: this does not impact on the CEO avg age currently.
C: These companies have been operating for at least 20yrs. Thus, this cannot represent the general companies. CORRECT.
D: No impact.
E: Not necessary for this number.

I got stuck between C and E.

A is out - it is irrelevant
B - irrelevant
C = looks good, we make a generalization based on a limited sample. this is a major flaw.
D - approximate information given - well, tempting, but not. C is more strong.
E - the number of companies in the sample is irrelevant.

C for me

i m confused this is weaken question why are some posts based on inference , to weaken a conclusion we have to add new information and making the assumption false, C cannot be the assumption , In C we are given with the fact that is already stated in question.

Expert please correct me if i am missing anything.

This is a weaken question. We have to find the conclusion and weaken it.

Premises:

The average age of CEOs in a large sample of companies is 57.
The average age of CEO’s in those same companies 20 years ago was approximately eight years younger.

Conclusion: CEO’s in general tend to be older now.

Notice what the conclusion says: CEOs IN GENERAL tend to be older now. How can you deduce something about CEOs in general now when you have researched CEOs of only those companies which were in operation 20 yrs ago too. What about all the companies that came up in the last 20 years? What if the CEOs of the younger companies are much younger. Then the conclusion weakens. Option (C) points out this flaw in the reasoning. Hence it weakens the conclusion.
